Liaoning liquid crystal mosaic manufacturers, Gansu LCD Video Engineering, Beijing 42-inch large-screen LCD splicing machine itself in order to increase the standby time and enhance LCD flashed a drive just tune, LCD manufacturers have developed to meet the low voltage and low frequency conditions using low the threshold voltage of the liquid crystal. It has the following features: time low threshold voltage of liquid crystal monomer with polar groups in the monomer without polar groups presents homosexual representation isomer chromatography conditions under standing shorter. More monomer component with a polar group, also means more liquid water molecules as well as a brief liaison with other free ion polarity, then dropped LCD capacitive resistance, leakage current and power consumption and resulting increase great. When the molecular chain polar liquid monomer in the UV intensified briefly coiled polar molecular groups constitute another neutral molecules, to become a non-smectic wrong situation, thus constituting the threshold voltage increases, the anchor of the guide layer the role of insensitive, low-voltage drive was lost tune. TN liquid crystal molecular chains are generally shorter than the characteristic parameter adjustment difficult, so the comparison is not the same characteristics significantly. STN STN LCD is the result of flash data model to calculate the length of the liquid crystal molecules, electrical and optical properties of the required parameters, and chemical makeup is similar to many of the molecular chain structure is not the same as having a single polar molecular groups, and assign each to a feature similar series of LCD. Not the same series of the STN liquid crystal generally has a completely different molecular chains, therefore, not the same series of the STN liquid crystal unless the manufacturer can be assigned to each other outside illustrate, not assigned to each other. Life expectancy with respect to the use of DLP and PDP, a liquid crystal is very long, and the power is low, less heat, the failure rate is very low. PDP plasma easy to attack plasma traces its dynamic flash may reach several tens of thousands of hours of life, but in the high-brightness flash of static pictures, maybe five thousand hours after the presentation screen will burn; and DLP bulb life expectancy is only three 1000-5000 hours, 24 hours on demand using a series of security monitoring large-screen mosaic wall selection, the selection should be thinking crystal mosaic wall, the use of power to trek down the use of capital and capital protection. DID flash skills are a new skill, high brightness, high contrast, high color saturation, high color uniformity and longevity number, even a short time, such as trouble-free features, which in many cases have to use, has a very good visual effect. Also has a flash of clarity, a larger viewing area, the share of adjustable flash, bright colors are bright and very thin body, the use of long life expectancy. Most of the early years of DID are single use flash screen approach, followed by science and technology to expand and trek, DID flash when its screen is now available for use narrow stitching (≤24mm), and you can get an excellent flash effect. DID splicing due to the use of a thinner body, can be considered the user to save more space to use, simple and convenient splicing combinations, using the DID mosaic wall can be said to receive less funding excellent flash effects and high cost. Mall security demand, LCD Video commodity worthy of attention. Original, mall security has been reflected in the various areas of our country. For example, the fire command center public relations business information systems, logistics company's business dispatch center, command and reconcile large-scale performance conferences, radio and television flash. Along with the industry to create the continuous development of information technology, user demand for security monitoring also will strong, at the same time, provide a set of talented information technology business solutions for the security category of users even more critical. Huakai Rui Technology (country) Limited hukairuiLCD, UX and UT series LCD splicing screen, is exclusively developed by our company are widely used in all types of environmental engineering splicing dedicated display. Using the occasion include: education, presentations, multimedia web conferencing, e-commerce, work reports, telemedicine, commodity exhibitions, training, military command and commentary, research, engineering, project planning, securities commentary, entertainment and studio, sports, maps, weather , astronomy, vehicle scheduling, interactive presentations, hotels, colleges, primary and secondary audio-visual education and long-distance education and other places.
